000015057 520__ $$2eng$$aWe explore the fracture toughness of a polymer gel containing a Mode I growing crack. First, an expression is derived for the energy release rate within the linearized, small-strain setting. This expression reveals a velocity independent toughening that stems from the poroelastic nature of polymer gels. Then, we establish a poroelastic cohesive zone model that allows us to describe the micromechanics of fracture in gels by identifying the role of solvent pressure in promoting poroelastic toughening. We confirm our theoretical findings by means of numerical simulations.
